Title: 不揮発性メモリにおける妨害の低減方法
IPC: G11C16/02
Filed: 2001-10-26
Abstract: 不揮発性メモリにおいて、変位電流が非選択ワードライン内に生成され、アレイのビットラインに対する電圧レベルの変更時に結果として生じるこの変位電流により、結果的に妨害が発生する可能性がある。これらの電流を下げる手法が提示される。第１の局面では、ワードライン上で同時にプログラムされるセルの個数が減らされる。メモリセルアレイが複数のユニットから構成され、これらのユニットを組み合わせて、共通ワードラインを共用する平面に変える不揮発性メモリでは、同一平面内のユニットの同時プログラミングが回避される。複数ユニットの同時プログラミングも可能であるが、これらのユニットは別個の平面に存在するように構成される。上記第１の局面は、プログラムを行う対象ユニットを比較して、いずれのユニットが同一平面から得られたユニットであるか、あるいは、いずれのユニットが上記ユニットの組み合わせであるかを調べることにより、同時にプログラムする対象ユニットの数および当該ユニットの順序を選択して、まとめてプログラムするすべてのユニットを別個の平面から得るようにすることより行われる。第２の相補的局面では、ビットラインに対する電圧レベルの変化の速度の調整が可能である。妨害周波数の監視を行うことにより、あるいは、デバイスのアプリケーションに基づいて、ビットライン・ドライバがビットライン電圧を変化させる変化の速度の調整を行うことが可能となる。上記第２の局面は、デバイスのパフォーマンスおよび生成されたデータエラー量に基づいて、コントローラにより外部で上記速度の設定を行うことにより実現可能である。
